WINDOW.

Patented Mar. 17. 1914.

Application filed August 2, 1913. Serial No. 782,631.

T 0 all whom it may concern Be it known that I, IVILLIAM Hoo1i,`a subject of the German Emperor, and resident of the city of New York, in the county of New York and State of New York, have` invented certain new and useful Improvements invVVindows, of which the following is a specification.

The present invention relates to windows, and has for one ot' its objects to provide a sash which can be easily and conveniently reversed so that its outside can be readily cleanedor repaired when desired.

Another object of the invention is to provide a sash with double panes, whereby, when said window is properly closed, the entrance of cold air into the room is effectively prevented.

A further object of the invention is to construct a window, the sashes of which are arranged in the saine plane when the window is fully closed. v y

With these and other objects in view, which will more fully appear as the nature of the invention is better understood', the same consists in thev combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion ofthe several parts and details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illust-rated in the accompanying drawings, in which l Figure 1 isa front elevation of the iinproved window; Fig. 2 is a vertical section taken therethrough; Fig. 3 is a similar section with the lower sash swung inwardly; and Fig. 4 is a section taken on line 4-4 of Fig. 2.

In the drawings, the numeral 5 indicates a window frame, to the inner vertical surfaces of which are attached in any suitable manner guide strips 6, 6, connected at their upper ends by a horizontal strip 7. The strips 6, 6 extend downward to aboutthe middle section of the window frame, torming thereby grooves S, 8, in which the upper window sash 9 is slidably arranged. The lower window sash 10 is provided with a groove 11 in its lower horizontal rail 12, in which groove is normally Seated a weather strip 13, the latter being att-ached in any suitable manner to the window frame.

Each of the sashes is composed of two sections, which are held together by screws 14, 14, engaging their stiles 15, 15. Between the two sections of each sash is arranged a frame 16, holding the inner window panes 17 upon the inner sections of the sashes, while the outer window panes 18, 18 are kept upon the outer sections in the usual manner by putty, or otherwise. The lower lrails 19 of the sections of the upper sash are beveled to fit the correspondingly beveled edges'20 of the upper rails 21 of the sections of the lower sash. Sash cords 22, 22 are attached, to one of the upper rails 21 of the lower sash, passing over pulleys 23, 23, and -carrying weights 24, 24, which are slidably arranged in guideways 25 upon the vertical sides of the window frame; said sash cords passing from thence toward the upper rails of the upper sash, and being attached to one of the same at 26, 26 in any suitable manner.

Alsash lock 27 is provided, said lock comprising a bolt 28, rotatably arranged in the upper rails 21 of the lower sash andhaving a handle 29 upon the inner side of the window facilitating the rotation of this bolt. The inner end of this bolt carries a cam 30, adaptedto engage a recess 31 in the lower rails of the upper sash when said two sashes are arranged in the same plane, as shown in Figs. l and 2 of the drawings.

To the vertical portions of the window frame are by means` of hinges 32, 32 fastened guide boards 33 for the lower sash, said guide boards being normally arranged in planes parallel to the window panes, and

being held in such positions by means of locks 34, 34. To the guide boards 33, 33 are attached above the lower horizontal portion of the window frame trapeziform guiding blocks 35, extending in-'planes at right angles to the planes of the guide boards 33, 33 for a purpose which will be hereinafter described. The inner vertical edges 36 of these guide blocks abut against the lower rail of the window sash 10 when the latter is in its normally closed position, the edges 37 of the blocks extending at an acute angle to the said edges 36.

The operation of this device is as follows: The 1window is shown in its closed position in'Figs. 1 and 2 of the drawings. In ordei` to raise the lower window sash, the sash lock 27 is opened and the upper end of the lower sash turned inward toward the guide boards 33, 33. In raising now the upper end of the sash, its lower rails will slide up the edges 37 of the guide blocks 35, after which the movement of the lower sash will be guided by the guide boards 33, 33 and the guide strips 6, G. 24 will hold both sashes in any desired positions.

lVhen the window panes of the lower sash are to be cleaned, the locks 34, 34 are opened, and the guide boards 33, 33 swung into the positions shown in Fig. el in dotted lines, the guiding blocks 35 swinging with the same. When now the eam is disengaged from its recess 31, the lower sash can be swung inwardly into a horizontal position, as clearly shown in Fig. 3 of the drawings, its lower end resting then upon the lower hori- Zontal portion of the window frame. To clean the panes of the upper sash, first the lower sash must be raised so that its upper rails will contact with the inner face of the upper horizontal section of the window frame, after which said upper sash can be The sash weights 24,'

swung into a horizontal position, the length of thesash cords 22 permitting of such operation.

The guide blocks 35, serve to bring the lower sash by means of their inclined surfaces 37, 37 into its proper position from its upper open position.

A window sash comprising two sections, each section including two Stiles, an upper and a lower rail, the stiles and rails of said two sections contacting throughout their lengths, the contacting sur-faces of each section being recessed, a window pane mounted in the recessV of one section, a frame located in the recesses of both sections for holding said window pane in one of said sections, and a window pane mounted in the other section.
